MACHINE FOR EXAMINING TEXTILES.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed November 26, 1917. Serial N 0. 203,997.

To all whom it may concern:

Be it known that I, FREDERICK E. PARsLon, a citizen of the UnitedStates, and resident of Milwaukee, in the county of Milwaukee and Stateof lVisconsin, have invented certain newvand useful Improvements in Ma--chines for Examining Textiles; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates broadly to improvements in machines for examiningtextiles, such as woolens, cottons or silk cloths of any texture, andmore particularly to an apparatus for unwinding, examining, measuringand refolding cloth, which will require only. one operation.

To those skilled in the art to which this invention belongs it is wellknown that it is necessary to closely examine all cloth before it cut upin order to determine Whether or not it is in any way defective. Theusual method of doing this is to unfold the fabric and drape it over asuitable bar or the like before a strong light, either artificial ornatural, this being customarily done by hand.

Therefore, it is the object of the present invention to accomplish thisexamination with a saving of time and labor, this being readilyaccomplished in 0118' machine con structed in the manner illustrated.

An object of the invention subsidiary to the principal object is toprovide a novel arrangement for automatically folding the cloth afterthe examination thereof the speed of such folding operation beingproportionate to the rapidity of the examination.

A still further object of a minor nature is to provide a measuringinstrument in connection with the other features whereby the amount ofcloth examined can be-accurately determined. 1

Another object is to provide means for controlling the speed ofoperation of the parts which move the cloth into position forexamination thereof.

Still another object is to provide a device whereby double folded clothmay be spread to its full width before being disposed for itsexamination.

lVith these and other minor objects and advantages in view the inventionresides in the novel features of construction. combination andarrangement of parts which will be hereinafter more particularlydescribed and claimed, and shown in the drawings wherein:

Figure 1 represents a front elevational view of a machine constructed inaccordance with' my invention.

V Fig. 2 is an end elevation, partly in section. of the machineillustrated in Fig. 1.

Fig. 3 is a plan view of this improved machine with certain of theelements removed for convenience in illustration.

Fig. 4 is a vertical transverse section taken on the plane of the line Hof Fig. 1.

Fig. 5 is a detail vertical longitudinal section on the line 55 of Fig.9, showing particularly the means for varying the speed of operation ofthe cloth feeding means.

F ig. 6 is a detail sectional view taken on the line 6-6 of Fig. 2, and

Fig. 7 is a fragmentary elevational View of the means for adjusting thecloth examining member.

The invention comprises broadly a supporting frame of a suitable type, acloth examining member pivotally mounted on said frame, means for movingthe cloth over said examining member, means for measuring the quantityof cloth so moved and .means for folding the examined cloth. All

of these features of the invention will be independently described andtheir relation to one another explained.

A supporting base may be of any suitable or convenient design, but thatillustrated has been found to work advanta geously. It comprises a pairof end frames 1, each of which is constructed substantially of threeangle bars arranged in the form of a triangle, one of the sides 2 ofwhich rests upon the ground thereby disposing the apex of the triangleupwardly. The sides 3 of the frames 1 are braced intermediate their endsby the bars 4, and the base bars 2 are connected with similar channeledbars 5 each serving to space the end framcsapart, and at the same timeholding them in rigid relation. p

The upper endsor apices of the frames are connected by trunnions 6 of afeed roll 7, said trunnions being journally mounted in suitable bearingscarried by said end frames. A textile examining member S is tiltablymounted on the supporting base by means of said trunnions 6, saidexamining member comprising a rectangular frame 9 preferably formed ofangle bars which 7 carry a transparent plate 10 such as of glass.

The opposite end bars of the frame each has a segmental plate 11 securedthereto, said plates being provided with alined openings for thereception of said trunnions 6.

The arcuate edges of the plates 11 are cut to provide rack teeth whichmesh with the teeth of pinions 12 that are carried by a shaft 13 alsojournally mounted on the end frames 1. Also fixed on the shaft 13 is aratchet wheel 1% with which a pawl 15 engages to prevent retrogrademovement'of the shaft. By this arrangement the examining member 8 may betilted from a horizontal. to. a substantially vertical position or to.any intermediate point and held thus.

This movement is obviousl r effected b Y rota-,

tion of the shaft 13 in the proper direction which causes the segmentalplates to shift around their axis. The examining member being pivotedintermediate its .ends and nearer one end than the other, theoverbalanced portion thereof will tend to cause the shaft 13 to revolvein one direction, said tendency being overcome by the pawl and ratchetarrangement.

The cloth to be examined is conveyed across the upper face of thetransparent plate 10, this movement being facilitated by a guide roller16 journaled in suitable bearings carried by the upper end of the frame9 of the member 8. This roller 16 is of course positioned transverse ofthe direction of the movement of the cloth, and at the opposite end ofthe frame is similarly positioned a second guide roller 17, this rollerbeing journally mounted in brackets 18. The freedom of movement of theroller 16 is controlled by a spring tension device consisting of a wheel19, a leaf spring 20 and a set screw 21 for adjusting the spring towardand away from the wheel. These parts are shown in -lTigs. 1, 2, and l.

The brackets 13 also have a third guide roller 22 carried thereby, saidguide roller together with the roller 17 and the feed roll 7 cooperatingto move the cloth from the upper edge of the frame 9 to a point beneathsaid frame where it can be operated upon by the folding means to behereinafter more particularly described.

A plurality of feed belts 23 are disposed around the feed roll 7 and theguide roller 22 as shown, theupper stretchlieing engaged by the guideroller '17. The lower stretches of the belts are engaged by tensioningdevices, one of which is provided for each of the belts. Theseten'sioning devices are mountednpon a shaft 2a, the latter in turnbeing'carrie'd by the segmental plates 11. Each device consists of aroller 25 for engagement with a belt 23, an arm 25 for "pivoting'saidroller-.25 to the sh aft 2-f, and

a coiled spring 27 engaged with said arm 26 for moving said rollertoward the belt.

The feed roll 7 is revolved by any suitable power supplying machine,belted or otherwise connected with a pulley wheel 28, which is mountedon a stub shaft 29 carried by one of the end frames 1. The pulley wheel28 is preferably clutched to theshaft to be controlled at the will ofthe operator of the machine as shown by the arrangement at 30 in Fig. 1.This clutch arrangement is actuated by the longitudinal sliding movementof a foot bar 31 which is disposed on one of the brace bars 5 of thesupporting base. It will be noted from Figs. 1 and 3 that the barthroughout its length is provided with a number of sets of projections32's0 that the same may be actuated by the operator regardless of hisposition with respect to the ends of the machine. The movement of thebar 31 is obviously transmitted to the clutch mechanism by theintermediately pivoted lever 33 mounted upon a bracket 3-1 projectingfrom one of the end frames 1.

The speed of rotation of the feed roll 7 with respect to the pulleywheel 28 is readily varied by a suitable friction clutch comprising apair of plain gear wheels 35 and 36 mounted respectively upon the shaft29 and one of the trunnions 6 of the feed roll, and a shiftable frictiongear 37. The gear 37 consists of a pair of circular plates 38 spacedapart to receive the gears 35 and 36, said plates being disposed on astub shaft 39. The plates 38 are moved toward each other so as totightly engage the friction wheels by an adjustable spring 10.

The shaft 39 being carried by a lever 41-1, the friction gear 37 isreadily moved toward oraway from either of the shafts 6 and 29. Suchmovement of the lever 11 is controlled by either one of a pair of bellcranks -12, one

of which is fixed to each end of a shaft 43 that extends longitudinallyof the machine and across the front thereof. One end of each bell crankforms a handle while the other arm of one is linked as at 14: to thefree end of the lever &1. Thus the speed of the feed roll can becontrolled from either end of the machine.

The lever 41 is held against jarring out of its adjusted positions bythe arrangement shown in Fig. 6 which consists of a spring pressed plate45 and a strip of non-metallic anti-slipping material 4:6, both of whicharesecured to the end frame by the bolts 47. The lever a1 isfrictionally held between the plate 4E5 and the strip 16.

Inasmuch as most woolens and suitingmaterial are rolled or folded indouble thick ness, it must be unfolded before being exam; med, thereforeI have provlded a Ll-shaped.

guide rod 48, the arms 'of which are pivotally mounted on the ends ofbrackets lti which extend from the opposite ends of. the

frame 9'. The ends of the arms which extend through said brackets49'arethreaded to receive nuts whereby the rod may be held in adjustedpositions with respect to the frame 9.

The cloth as it moves over the examining member 8 is measured by anyconveniently formed measuring device such as that shown at 51. Thisdevice is geared to the feed roll 7 in any desirable manner, it beingmounted on one of the end frames 1 adjacent one of the trunnions 6 bymeans of a bracket After the cloth has been moved over the examiningmember by the feed roll and the feed belts it is folded upon the floorbeneath the machine or upon a. suitable table disposed thereunder. Thisfolding device consists of an oscillatory plate 58 hinged to the shaft13 and extending the full length of the machine. The plate is oscillatedby means of a crank 54 connected with the same by a pitman 55 as shownclearly in Fig. 1. The crank is connected with a shaft which iscontinuously revolved with the feed roll 7, it being connected therewithby a belt 56. Thus whenever the speed of rotation of the feed roll ischanged, the oscillation of the plate 53 will be proportionately varied.

The cloth as it passes over the feed roll is guided on to theoscillatory plate 53 andhcld against movement between said roll and theshaft 13 by a plurality of guard strips 57, the opposite ends of whichare disposed around the feed roll and shaft 13 respectively. Said feedroll is covered by any suitable friction material, such as finesandpaper or felt to prevent slippage of the cloth.

The operation of my invention with double folded cloth is as follows:The cloth examining frame is tilted to the convenience of the operatoror to permit the strongest light to be thrown through the transparentplate 10, such adjustment of the frame being accomplished ashereinbefore set forth. The bolt of cloth is then disposed adjacent theguide 48 and the end of the strip disposed between the arms of saidguide with the seam thereof resting in its apex. The

portion of the cloth on each side of this fold will then lie on the armsof the guide, after which the end of the strip of material may be movedupwardly, over the guide roller 16.

and across the upper face of the member 8, fter which it is directedaround the guide roller 17 and on to the upper stretches of the feedbelts 23. Continuation. of movement of the end of the strip of cloth tobe examined disposes it on the feed roll 7 and oscillatory plate 53.Vfhen the rotation of the feed roll 7 is begun by actuation of theclutch 30 the cloth is moved across the transparent plate 10 to permitthe light disposed beneath the same to shine through the cloth and thuspermit detection of defects therein. Thus the cloth is automaticallyunpackaged and after the examination is complete is folded into aconvenient and uniform pile. As some cloth can be examined much morerapidly than others, therefore the above described means for varying thespeed of rotation of the feed roll has been provided.

The simplicity of this machine is obvious from I examination of theaccompanying drawings and its effectiveness is believed to be thoroughlyevident after an examination of the drawings and the accompanyingdescription. I l
